|About the stats|
Over the course of his career, Billy McCool pitched 528 innings and made 109 plate appearances. McCool was worth 4.6 Wins Above Replacement (5.5 as a pitcher and -0.9 as a hitter) and -0.4 Wins Above Average (0.6 as a pitcher and -0.9 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.6 WAR becomes 5.8 adjWAR. Then, WAA is adjusted by ignoring negative seasons (thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers. After these adjustments, the -0.4 WAA becomes 4.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McCool 13.7 wWAR. wWAR is then converted to Hall Rating. A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).
Billy McCool has a Hall Rating of 13, leaving him nowhere close to induction to the Hall of Stats.
